Abstract
A single use, disposable reservoir of low volume for use in conjunction with a spray gun for spray painting small areas, for example ‘spray out’ cards for color matching a paint mix for spray painting a vehicle. The reservoir is in the form of a syringe body with a plunger having a sealing member slidable within the body for drawing paint into the body via an open end. The body has an aperture adjacent to a closed end and the plunger can be moved to position the sealing member between the aperture and closed end for releasing a partial vacuum created when the paint is drawn into the body and allow the paint to be withdrawn, in use, when the reservoir is connected to a spray gun without actuating the plunger. In other embodiments, the reservoir comprises a concertina-type body or a pipette body.
